1.4.3.2 Energy Saving (V/f Save Energy)

The function allows to reduce the motor Flux in order to reduce the losses.
As a consequence it is possible to obtain an energy saving when the load requires a reduced torque as compared
to the rated one (save energy).
Through the input sources it is possible to select the origin of the save energy command signal and of the signal
stating the flux level.
The sources are:
-SE cmd src
-SE flx level src
In the configurations it is possible to set via Int SE flx level an internal percentage value stating the flux level and
via SE flx ramp time a ramp time on the level.

It increases the output voltage with low frequencies in order
to compensate the voltage drop on the stator. It avoids the
torque loss with a low output frequency.
It compensates the speed change due to the load increase
considering the slip value.
Filter on the slip compensation. It avoids oscillations due to a
It allows to damp the current oscillations between the motor
and the DC link, which could be developed in the middle
range of the rated speed.
